In 2009, under the leadership of Professor Xu, a group of outstanding math teachers from the former Beijing Hualuogeng Mathematics School set up a "top math class", which initiated the expansion of domestic extraordinary education outside the public system. The "Top Class" has been running for eight years and has trained more than 9,000 students. Students who have received top-level training not only have obvious advantages in entrance selection and various competitions, but also show strong learning ability and development potential in the subsequent learning process of middle schools and even universities, winning unanimous praise from parents and students and forming a good reputation and extensive influence in society.

With the rapid development of social economy, the education and training industry is also moving forward in the process of change. In order to actively adapt to the changes in the industry and let more extraordinary children fully benefit from the high-quality educational resources in the top class, the teaching and research team of more than 20 people based on the core members of the top class established the "Gaosi Extraordinary Education School" in February 2009. The establishment of Gaosi Education marks a brand-new page in the history of Gaosi team. Gaosi will upgrade the teaching hardware environment in an all-round way and establish a high-quality customer service system. At the same time, on the basis of maintaining the fine tradition of teaching and scientific research, we will further strengthen the related work in courseware research and development, textbook publishing, teacher training, information service, distance education, etc., and gradually build Gaosi into a well-known brand in the field of extraordinary education.
